2. Monthly demand at A\&D electronics for flat-screen TVs are as shown. Estimate demand for month 13 using simple exponential smoothing with =0.3 and Holt's model with =0.05 and =0.1. For the simple exponential smoothing model, use forecast for F1=1,634 (the average demand over the 12 months). For Holt's model, use F1=980 and T1=101 (both obtained through regression). Evaluate the MAD, MAPE and MSE for each forecast. Which of the two methods is more accurate? Why
